那个男人一定是我们的校长。 —No, it can’t be him . He is holding a meeting now . 不,不可能是他,他正在主持会议。
may / might 1. 表示请求和允许 。 might 比 may 语气更委婉,而不是过去式。否定回答时可用can’t 或 mustn’t , 表示“不可以,禁止” — May I smoke in this room —No , you can’t / mustn’t . 2. 表示推测 ,谈论一种可能性 ,多用于肯定句中。Your mother may / might be very busy now.

must / have to 1. must 必须 must 引出的一般疑问句时,否定回答用needn’t / don’t have to 不必—Must we hand in our homework today —No , you needn’t / don’t have to . / Yes , you must .2. must 是说话人的主观看法,而have to 则强调客观需要。must 只有一般现在时, have to 有更多的时态形式。3. must 表示推测 ,指可能性较大 “一定”用于肯定句中。
must / may / might / could / can’t 表示推测的用法 must 可能性最大,“一定” might / may / could 可能性较大 “可能” can 否定意义的推测 “不可能”
情态动词表推测时,用不同的形式表示不同的时态。 表示对现在情况的推测用“情态动词+动词原形” 表示对正在发生的事情的推测用“情态动词 + be doing ” 表示对过去或完成事件的推测用“情态动词+ have done”
